I overheard some friends talking about buying a used car. One said to make sure that no one had put sawdust or banana peels in the oil! Now I had heard this statement or something similar years ago and had forgotten.
My question is how would this help or mask the symptoms a tired worn out engine? All I can see it doing it plugging the oil pump pickup and locking up the engine? I guess all this stuff could help plug leaks in gaskets/seals to mask an oil leak but what good would this really do? Is this just an old saying or was this actually done at one time? I can see it maybe working on an engine without an oil pump (really old) but cannot see it doing anything good, even in the very short term, on a modern engine.
